- AEM 6.5: versions 0 to 6.5.25 (per CNA record)
- AEM Cloud Service: applicability to this CVE unconfirmed; earlier builds than 2026.9.28386 are listed as affected in the bulletin context
- Unknown: exact row mapping in Adobe bulletin APSB26-152 for this CVE
Fixed in
- AEM Cloud Service: 2026.9.28386 or later (per Adobe bulletin APSB26-152, applicability to this CVE to be confirmed)
- AEM 6.5 LTS SP1 to SP3: hotfix NPR-44637 (per CNA record)
- AEM 6.5 versions 6.5.20 to 6.5.25: hotfix NPR-44636 (per CNA record, to be confirmed against the Adobe table)
Workaround
- No vendor workaround known.
- Restrict access to author and admin interfaces until patched.
- Limit accounts to trusted users and review existing accounts.
Exploitation
- Adobe is not aware of any exploits in the wild for issues in this update.
- No public proof of concept found for this CVE.
- CISA SSVC assessment: exploitation none, not automatable, total technical impact.
- KEV status: unconfirmed.
Our recommendation
- Identify all AEM instances (Cloud Service, 6.5, 6.5 LTS) and their versions.
- Confirm in Adobe bulletin APSB26-152 which fix applies to CVE-2026-75732 for each product line before patching.
- Patch internet-facing and author instances first and review user accounts and recent logins.
- Prioritise the whole bulletin, as it contains further critical CVEs.
- Re-check NVD and the CISA KEV catalogue, as NVD analysis is still pending.
